Tomapowa...Do you run 30% in that baby?

Thanks
Barry

Even better.... 100% (100% Lithium Polys... 12 cells, 6s2p, 22.2v, 4200maH)
Should have 2:1 thrust to weight ratio...

OK... maybe you fellas are not ready for electrifying yet... Here's a pic of my Nitro version... (0S-70)


This better ???

Yeah, that looks better. 63?

Thanks
Barry

HY MANS,,

I´M LOSE FOR A FEW MONTHS, BUT I´M LIKE THE BEARS IN WINTER AND I´M BUILDING A NEW BABY...

MY UCD IS WAITING FOR SUMMERS DAYS, I THINK NEXT WEEK I TO BEAT OUT THE DUST OF THE WINGS.

HERES SOME PICTURES OF MY NEW WINTER CONSTRUCTION...

SERGIO

No, shown in the pic is an OS-72 (no pump but it runs like it has a pump!.. no kiddin)
Plenty of power too, running YS 20/20 fuel (I love oil) spinning an APC 15x5.5 prop, 1/2+ throttle hovers.
I have a YS-63 and was going to put it in the airframe which I am now converting to electric.
Supposedly, the YS-63 packs a little more punch.

ST G90, IT´S GREAT AND HAVE A LOT OF POWER. BUT I NEED TO KNOW HOW CONFIGURATION IS THE BEST TO DO ELEVATORS AND GOOD FLAT SPINS..

SERGIO

ST G90 !?!?!?

Your CG must be way up front... might have to add oz.s of lead in tail to get CG back far enough...

Sergio, are you asking for the UCD? I thought you already mastered the flatspins, but if not (this is just an estimation since i crashed mine) but i never got mine to do elevators because i think there is too much wing area to let it drop without stalling one wing(wing rock) but flatspins are a diffrent story, it does them great, the inverted flatspin better, my cg was at 5.75in and all the elevator i could get and all the rudder i could get, alierons will work with moderate settings to stabilize the wings horizontally in spin

nice Edge, where did you get that? and i like the canopys two tone[8D]

Hey nice plane Sergio..........[8D] Very nice.........[X(]

hey, guys has it going?
I haven't been flying far 3 weeks[:@]

My Father and i helping our club president move in to his new home.

hes moving closer to the field
so we well not bi flying for a month

then after that we are going to be working on our trailer and a friends at the same time ang that will take 2-3 saturdays[:'(]
so have fun flying


38

you must have a veryyy great father 38, stick with him (might just pay off)[X(]

winds been blowing here for my first weekend with my son in 6 weeks[:@]

Rob, you arent wasting all that great weather up there are you

Hey fellas,

Been quite for a while now, havent gotten much flying in due to rain rain rain. Yesterday was a nother rainy day, but when i woke up i decided to take my chances since there werent any drops at the time.

Well I got one flight in a light drizzle. BUT THAT FLIGHT WAS SO WORTH IT. I have been messing around with flat spins and got my first real flat spin. It was an upright flat spin and i felt like I could have left it up there and come back later. It was awesome. About 30 seconds later the drops got bigger and I brought her down. About 3 feet short of the runway. DOH!

But that was good because i rebuilt the landing gear and it held up to the rough terrain.

The season is drawing close to an end hear, i hate winter. Hopefully i get my Golberg Ultimate built this winter.

gjeffers

I do

and i will

thanks

TAMAPOWA, FOR THE CG I PUT THE BATERIES UNDER THE ELEVATOR.

GJEFFERS, A FEW MONTHS AGO YOU TELL US HOW TO DO FLAT SPINS AND WHERE YOU READ ABOUT IT, BUT ON THAT TIME Y TRY TO DO BUT I CAN´T[&:] WITH OTHERS PLANES A CAN BUT WITH UCD NO. , THEN THE WINTER COMES AND I DON´T FLY AGAIN UNTIL NOW.. YOU TELL WE HAVE TO PUT THE AILERON ON 45° = RUDER BUT I TRY AND COULDN´T, TODAY I LOOK MY CG (I DON´T REMEMBER) AND TELL YOU.. . THE PLANE OF THE PICTURE IS AN EXTRA 300 27% CAMODEL NOT AN EDGE. AND I ALWAYS PAINT THE CANOPI, ITS MAKE THE PLANE LOOKS MORE STRONGER..(I THINK). SORRY FOR YOUR CRASCH BUT I THINK YOU HAVE ANOTHER, AND CONTINUE TEACHING WE. I THINK I HAVE TO READ ON THEES FORUM, WEAR YOU CRASCH

SERGIO

What great weather?
[:-] It's gotten in to the typical fall weather here now and it's truely Forest Gump type stuff, "you never know what you gunna get"
It tends to get rainy/stormy here untill about December and then can turn nice again for a while. It's a crap shoot though.
I've got a Mayhem heading my way. Should have it next week and have an OMP Edge kit to build while the weather's bad. I'm working this weekend.[>:]

WHAT OMP EDGE DO YOU HAVE ???

SERGIO

Sergio, I have the OMP Edge 540 profile. It's a 40 size profile kit. [8D]

sorry Rob, didnt mean to stir ya up, weather here was great all week and as soon as me and Brock got out to the field it started blowing, but today when the weatherman said it was going to blow to all hadies it was nice so we did get to fly today, thank the lord cause the weatherman dont know hoot!!!!!

nice EXTRA Sergio, (shows im not a pro but im trying)

CeeGee...I'll be interested to hear how you like your Mayhem. How are you going to set it up? Engine? Servos? Etc.?

THanks
BArry

No problem Gary. Didn't stir me up. [>:] I never used to get bummed about the weather but now that flying depends on it, well, DARNED WEATHER! Oh, I'm okay now........[>:]

Barry, Well I have a couple of servos and the RX but that's about it. The servos are Hitec 635HB. I need some advise on the engine choice. I don't think I'll go with a YS because I don't want to have to use a separate fuel or 30% or something. I'll probably go with a Saito but not sure if the 100 has enough poop and the 120 sounds quite a bit heavier for the size difference. ( the 100 weighs 550 grams and the 120 weighs 900 grams) Not sure if the difference in the 120 is good weight. What do you think Barry. I trust your experience....[8D]

Cee Gee...THe Mayhem will weigh less than 7.5 lbs with a Saito 100. If you are anywheres near sealevel it will be fine on that plane. But I think you should run 30% in all 4 strokes but you'll be fine with the Saito. If you run it with 15% you can always up it more if you're not satisfied. The YS is the perfect engine for me but I'm at 4800' elevation. I think I get Saito like performance up here. I think the Saito would be a good choice.

Thanks
Barry

Thanks Barry. I think I fly at more like 48 ft. not anyway near 4800. It sounds like it would work good though. I have a hard time thinking about using 30% though. That's probably about 30 bucks a gallon[X(]. Yikesters! Curls my nose hairs just thinking about it......[:-]

You can buy it from Tower with all discounts and freight and special charges and etc. etc. etc. it works out to about $25/gallon. But the 15% for me has be about $20/gallon. I also think you use slightly less fuel with 30%, at least I think I do. To me I rationalize it to be $3-$4/gallon more to run 30%. To me, that amounts to less than $75/year for sure. Probably more like $50. To me it's worth it. You will notice a major difference in power, not only peak power but also in crispness of transition. Way better.

Another thing, some people have complained about the Saito throwing the rear main bearing. The 30% fuel (at least if you use Cool Power Heli) has 22% oil. The 15% has 18% oil. (HUH????) Anyways, the heli fuel has a higher oil content which I believe give better bearing life. Also, with the heli fuel you don't need to run any after run oil. In fact they recommend against it. Another savings.

Thanks
Barry

Okay thanks Barry. Oh, I know. Christmas is coming up and can tell my wife "I need a case of cool power heli fuel" and she'll go "HUH"? What in the world is that?
